Information About Tennis Elbow Pain
Updated January 24, 2011
Tennis elbow, or lateral epicondylitis, is the most common injury in patients seeking medical attention for elbow pain. Exactly what causes tennis elbow is unknown, but it is thought to be due to small tears of the tendons that attach forearm muscles to the arm bone at the elbow joint.
Tennis Elbow Defined
Tennis elbow occurs when there is a problem with the tendons that attach to the outside of the elbow. These tendons are the attachment of the muscles that function to cock the wrist back. Specifically, the extensor carpi radialis brevis has been implicated in causing the symptoms of tennis elbow. This muscle attaches to a part of the elbow bone called the lateral epicondyle, thus giving tennis elbow the medical name 'lateral epicondylitis.' Tennis elbow is not simply an "inflammation" of these tendons. The problem is thought to be a degenerative process as a result of repetitive use. This process occurs when microscopic tears are incompletely healed within the tendon.
